7Pack .065" String Spool Compatible with Hart Auto-Feed String Trimmer Cordless Trimmers and Cover Cap Replacement Part,Replacement Hart Auto-Feed Pre-Wound Spool Line each 11ft (6Spools, 1Cap)

What It Is

This is a 7-pack of replacement .065-inch pre-wound trimmer line spools (6 spools, 1 cover cap) designed for Hart auto-feed cordless string trimmers. Each spool holds 11 feet of line, intended for light-duty trimming around edges, fences, and small lawns.

Fitment & Compatibility

• Line diameter: .065-inch (1.65mm) – for light trimming only; not for heavy weeds or thick grass.
• Compatible with: Hart auto-feed cordless trimmers (e.g., models 40V, 20V, and most 2-in-1 units). Check your trimmer model number against the seller’s list.
• OEM vs aftermarket: This is a third-party replacement, not Hart branded. It fits the factory spool housing but may differ slightly in cap engagement.
• What to measure before buying: Confirm your trimmer uses the “auto-feed” bump-head system, not a manual or fixed-line head. Measure the spool diameter and cap clip pattern if possible.

Key Things to Know

• Installation: Simple – remove old spool, snap in new one, replace cap. No tools required.
• Line quality: .065 line is thin; snaps easier than .080 or .095 on tough weeds. Expect to reload more often.
• Auto-feed reliability: Some users report the line may not feed consistently on first use; tap the head firmly on ground to advance.
• Cap fit: The included cap may be slightly looser than OEM; check that it locks securely before trimming.

Should You Buy It

If you own a Hart cordless trimmer and do light weekly trimming (grass, small weeds), this pack offers good value per spool. Avoid if you need heavy-duty line for thick brush or if your trimmer uses a fixed-line head – the .065 line will break too quickly. For the price, it’s a solid convenience pack for light users.
